Abstract

The invention discloses a clamping device, and particularly relates to a clamp for clamping the outer contour of a workpiece. The clamp comprises a clamp body, a left clamping jaw and a right clamping jaw which are used for compressing two side surfaces of the workpiece, and a screw rod which serves as a force application device, wherein each of the left clamping jaw and the right clamping jaw comprises an upper driven end for clamping and a lower driving end for applying force; the middle part of each of the left clamping jaw and the right clamping jaw is hinged on the clamp body respectively; a threaded through hole is transversely formed at the driving end of the right clamping jaw, and the screw rod penetrates through the threaded through hole and presses against the driving end of the left clamping jaw; and a return spring is arranged at the driving end of each of the left clamping jaw and the right clamping jaw. Compared with the prior art, the application device of the clamp is simple and ingenious in design, the screw rod is rotated clockwise to reversely drive the clamping jaws to rotate, and through the cooperation of the left clamping jaw and the right clamping jaw, the workpiece is clamped; and when the screw rod is reversely screwed, under the acting force of the return spring, the left clamping jaw and the right clamping jaw loosen the clamping of the workpiece and return to the initial state.

Description

A kind of anchor clamps of clamping work pieces outline
 
Technical field
The present invention relates to a kind of clamping device, be specifically related to a kind of anchor clamps of clamping work pieces outline.
Background technology
Clamping device is widely used for manufacturing.As to punching press, riveted joint, the welding of workpiece, paste or solidify etc. and usually need the position relationship that keeps correct in the process.Clamping device has various reference surfaces or point, and workpiece can accurately be located, so clamping device is considered to requisite parts in the processing industry.
For location and the clamping of miniature workpiece, usually adopt artificial free-hand finishing in order to reduce cost, by utilizing lever, spring, pulley, cam, the combinations such as jaw reach the effect of clamping work pieces.Although existing clamping device can satisfy the clamping demand of workpiece to a certain extent, when artificial hand operation, there are all multioperation inconvenience, the inconvenient application of force, can't suitably grasp the problem such as anchor clamps clamping dynamics.
Summary of the invention
The object of the present invention is to provide a kind of anchor clamps of clamping work pieces outline, be convenient to the application of force, and simple in structure, cost is low.
The present invention is achieved by the following technical solutions:
A kind of anchor clamps of clamping work pieces outline comprise chuck body, are used for the left and right jaw of workpiece pressing two sides, as the screw rod of force application apparatus; Described left and right jaw has comprised the top driven end and the bottom drive end that plays application of force effect of clamping action, and the middle part of left and right jaw is hinged on respectively on the chuck body; Laterally have tapped through hole on the drive end of described right jaw, described screw rod passes tapped through hole and offsets with the drive end of left jaw; Also be provided with back-moving spring on the drive end of left and right jaw.
Further, excessive for preventing left and right jaw clamping range, be provided with limited block between the described left and right jaw.
Those skilled in the art by common practise as can be known, of the present invention left and right be a kind of relative bearing concept, be not that absolute orientation limits.
The invention has the beneficial effects as follows:
Compared with prior art, force application apparatus design of the present invention is succinctly ingenious, thereby rotates by clockwise rotating the reverse drive jaw of screw rod, cooperatively interacts at left and right jaw lower, gets final product clamping work pieces; Oppositely turn screw rod, under the active force of back-moving spring, left and right jaw loosens the clamping to workpiece, returns original state.With regard to its building block, cost is low.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
By reference to the accompanying drawings shown in 1, a kind of anchor clamps of clamping work pieces outline comprise chuck body 1, the left jaw 3 that is used for workpiece pressing 2 two sides and right jaw 4, as the screw rod 5 of force application apparatus; Described jaw has comprised the top driven end and the bottom drive end that plays application of force effect of clamping action, and the middle part of jaw is hinged on respectively on the chuck body 1; Laterally have tapped through hole 6 on the drive end of described right jaw 4, described screw rod 5 passes tapped through hole 6 and offsets with the drive end of left jaw 3; Also be provided with back-moving spring 7 on the drive end of left and right jaw.In addition, be provided with limited block 8 between the left and right jaw.
Clockwise rotate screw rod 5, because its end and jaw 3 drive ends offset, force the jaw 4 that is connected with screw rod 5 to rotate counterclockwise along hinged center, thus clamping work pieces 2; Rotate counterclockwise screw rod 5, jaw 4 clockwise rotates under the active force of back-moving spring 7, loosens the clamping to workpiece 2, returns original state.
Above-described only is preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.

Claims (2)

1. the anchor clamps of a clamping work pieces outline comprise chuck body, are used for the left and right jaw of workpiece pressing two sides, as the screw rod of force application apparatus; Described left and right jaw has comprised the top driven end and the bottom drive end that plays application of force effect of clamping action, and the middle part of left and right jaw is hinged on respectively on the chuck body; It is characterized in that: laterally have tapped through hole on the drive end of described right jaw, described screw rod passes tapped through hole and offsets with the drive end of left jaw; Also be provided with back-moving spring on the drive end of left and right jaw.
2. the anchor clamps of a kind of clamping work pieces outline as claimed in claim 1 are provided with limited block between the described left and right jaw.
